A. B. C. D. E.

Correct Answer: C

STIntersection() method is used to return the point where two geometry instances intersect each other.

Example:

sa

DECLARE @geoml geometry;
DECLARE @geom2 geometry;
DECLARE @result geometry;

SELECT @geoml = GeomCol1 FROM SpatialTable WHERE id = 1;
SELECT @geom2 = GeomCol1 FROM SpatialTable WHERE id = 2
SELECT @result = @geoml.STIntersection(@geom2) ;

SELECT @result.STAsText();

Option A is incorrect.

Intersection is not the right function to return the point where two geometry instances intersect.

Option B is incorrect.

There is no function like GeoIntersection().

Option C is correct.

STIntersection() method is used to return the point where two geometry instances intersect each other.

Option D is incorrect.IntersectionPoint() is not a valid function in Azure.

Option E is incorrect.

STIntersection()is the right choice.

To return the point where two geometry instances intersect in an Azure SQL database, you should use the STIntersection() method. This method returns a new geometry instance that represents the spatial intersection of two input geometry instances.

Here is a more detailed explanation of the options provided:

A. Intersection(): This method is not a valid method for geometry instances in Azure SQL database.

B. GeoIntersection(): This is not a valid method for geometry instances in Azure SQL database.

C. STIntersection(): This method returns a new geometry instance that represents the spatial intersection of two input geometry instances. If the input geometry instances do not intersect, the method returns an empty geometry instance.

D. IntersectionPoint(): This method is not a valid method for geometry instances in Azure SQL database.

E. None of these: This option is not correct, as the correct method for returning the point where two geometry instances intersect is STIntersection().

Therefore, the correct answer is option C, STIntersection().
